### HTML Tables

### Status of this Memo

This memo defines an Experimental Protocol for the Internet community. This memo does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited.

### Abstract

The HyperText Markup Language (HTML) is a simple markup language used to create hypertext documents that are portable from one platform to another. HTML documents are SGML documents with generic semantics that are appropriate for representing information from a wide range of applications. This specification extends HTML to support a wide variety of tables. The model is designed to work well with associated style sheets, but does not require them. It also supports rendering to braille, or speech, and exchange of tabular data with databases and spreadsheets. The HTML table model embodies certain aspects of the CALS table model, e.g. the ability to group table rows into thead, tbody and tfoot sections, plus the ability to specify cell alignment compactly for sets of cells according to the context.
